A device for quickly freezing food product incorporates a pan and a base. The pan is adapted to receive the food product to be frozen, and has a bottom portion and a wall portion surrounding the bottom portion. The bottom portion of the pan has an upper surface and an opposing lower surface. The base is positioned under the bottom portion and the wall portion of the pan. The wall portion of the base is coupled to the wall portion of the pan such that the pan and the base form a unitary body. A cavity exists between the bottom portion of the base and the lower surface of the bottom portion of the pan. A plurality of fins project outwardly from lower surface of the bottom portion of the pan into the cavity.

1. A device for quickly freezing a food product, the device comprising: a pan adapted to receive the food product to be frozen, the pan having a bottom portion and a wall portion surrounding the bottom portion, the bottom portion having an upper surface and an opposing lower surface; a base positioned under the pan, the base having a bottom portion and a wall portion, the wall portion of the base being coupled to the wall portion of the pan, the bottom portion of the base having an interior surface, a cavity which receives a fluid medium is defined by the interior surface of the bottom portion of the base and the lower surface of the bottom portion of the pan, the bottom portion including a plurality of channel sections spaced apart to define a respective channel; and a heat sink positioned within the cavity to assist in freezing the food product, the heat sink thermally coupled to the pan to assist in freezing the food product and including a plurality of fins thermally coupled to the interior surface of the bottom portion of the base, the fins received in the respective channel of the bottom portion of the base. 2. The device of claim 1, wherein the heat sink comprises the plurality of fins to draw heat away from the food product and dissipate the heat into a surrounding fluid. 3. The device of claim 2, further comprising: a liquid in the cavity, the liquid contacting at least one of the fins of the heat sink, the liquid having a freezing temperature lower than a freezing point of water. 4. The device of claim 1, wherein the bottom portion of the pan is at least substantially flat. 5. The device of claim 1, wherein the bottom portion of the pan intersects the wall portion of the pan at an angle. 6. The device of claim 1, wherein the base is sealingly coupled to the pan. 7. The device of claim 1, wherein the cavity is located below the bottom portion of the pan. 8. The device of claim 1, wherein the cavity is located below and laterally outside the bottom portion of the pan. 9. The device of claim 1, wherein the fins are bonded to the pan. 10. The device of claim 1, wherein the fins are part of the pan. 11. The device of claim 1, wherein the liquid in the cavity only partially fills the cavity. 12. A method of freezing food products, comprising: providing a device of claim 1;cooling the pan to a temperature below the freezing point of water; andpouring a food base mix into the pan to freeze the food base mix. 13. The method of claim 12, wherein cooling of the pan includes providing the heat sink to draw heat away from the food base mix. 14. A device for quickly freezing a food product, the device comprising: a pan adapted to receive the food product to be frozen, the pan including: a bottom portion, the bottom portion having an upper surface and an opposing lower surface, a wall portion surrounding the bottom portion, and an engagement arrangement; a base positioned under the pan, the base including a bottom portion having an interior surface, the bottom portion including a plurality of channel sections spaced apart to define a respective channel, a wall portion surrounding the bottom portion, the wall portion of the base being coupled to the wall portion of the pan, and a receiving engagement arrangement, the receiving engagement arrangement configured to be coupled to the engagement arrangement of the pan, such that a cavity exists between the base and the pan, the cavity being defined by the interior surface of the bottom portion of the base and the lower surface of the bottom portion of the pan; a heat sink positioned within the cavity to assist in freezing the food product, the heat sink thermally coupled to the pan to assist in freezing the food product and including a plurality of fins thermally coupled to the interior surface of the bottom portion of the base, the fins received in the respective channel of the bottom portion of the base; and a liquid in the cavity, the liquid contacting at least the lower surface of the bottom portion of the pan, the liquid having a freezing temperature lower than a freezing point of water. 15. The device of claim 14, wherein the wall portion of the pan includes an external surface and an internal surface, the external surface being in contact with the liquid to assist in freezing the food product. 16. The device of claim 14, wherein the liquid is a urea-based freezing liquid. 17. The device of claim 14, wherein the liquid is a mixture of water and propylene glycol. 18. The device of claim 14, wherein the engagement arrangement of the pan projects outwardly from the wall portion of the pan and the receiving engagement arrangement of the base projects outwardly from the wall portion of the base, such that the engagement arrangement of the pan engages the receiving engagement of the base to secure the pan to the base. 19. A device for quickly freezing a food product, the device comprising: a pan adapted to receive the food product to be frozen, the pan including: a bottom portion, the bottom portion having an upper surface and an opposing lower surface,a wall portion surrounding the bottom portion, andan engagement arrangement;a base positioned under the pan, the base including: a bottom portion, the bottom portion of the base including a plurality of channel sections spaced substantially uniformly apart from each other to define a respective channel,a wall portion surrounding the bottom portion, anda receiving engagement arrangement, the receiving engagement arrangement configured to be coupled to the engagement arrangement of the pan, such that a cavity exists between the base and the pan;a heat sink positioned within the cavity, the heat sink thermally coupled to the pan to assist in freezing the food product and including a plurality of fins thermally coupled to an upper surface of the bottom portion of the base, the fins received in the respective channel of the bottom portion of the base; anda liquid in the cavity, the liquid contacting at least the lower surface of the bottom portion of the pan, the liquid having a freezing temperature lower than a freezing point of water, wherein the fins are configured in a substantially u-shaped cross-section having a base flange and upstanding legs on opposing sides of the base flange, each upstanding leg being thermally coupled to a respective channel section and the base flange being thermally coupled to the bottom portion of the pan.
